We've got bikes and we're getting more! Some of the most-popular bikes you still might have to wait for, but our staff will make sure your bike is so wonderful, so perfect for your needs and dreams, it will be worth the wait. Road, Hybrid, Mountain, Cruisers, Kids & E-bikes are arriving regularly. With Covid-19 situations seeming to change almost weekly, it's great to have something in life you can depend on... your new bike from Chain Reaction!

Note: We are still experiencing extreme peak-time demand, particularly on Mondays from 11am-1pm and nearly every day from 3:45pm until closing. We won't be able to answer the phone until all customers in the store are taken care of, and encourage you to send inquiries to and we'll get back to you later that day. Repairs also remain a major issue, due to the huge number of bikes finally arriving that customers purchased from us 6-12 months ago.

10/14 A quick word about masks- We're not out of this yet. Makeshift masks, including bandanas, are not allowed in our store. And even when San Mateo County says masks are no longer a "legal" requirement for indoor retail, we still may require them at Chain Reaction. We might not return to "normal" in the foreseeable future, and will take whatever precautionary measures we feel appropriate to protect the health of our staff & customers. 

Test Rides- Masks- Repairs! Repairs (updated 10/14)- How and when to reach us- All the answers here!

Our secret weapon! Karen & Becky keeping you updated and working with Trek to get your new bike as fast as possible!(Updated 06/01/20) GETTING YOUR NEW BIKE- OUR SECRET WEAPON! Most everyone knows bikes are in short supply by now; KCBS came by to do a news story featuring us. We have 1300 bikes on backorder right now. Just our single shop. 1300 bikes scheduled to arrive between now and 2023. We work with Trek daily, studying availability dates and creating a list that shows which bikes are coming in, and when. If anything's changed, Becky and Karen send emails with the updated status, often more than 50 in one session. Sometimes they get to make people really happy and tell them their new bike is coming in sooner than expected! And sometimes they have to deliver the bad news that delays at the port in Long Beach have added a week or two to the delivery time.
One thing is absolute. Once you place an order with Chain Reaction, nobody gets to cut in line in front of you, and, if someone changes to a different model, everyone else in line for that bike moves up one place. This means you never have to worry that a bike might come in that you want but somebody else snags it. You place an order, once, and we do the hard part.

Just a few of the bikes we sell. One of them is just right for you!
